Fast Facts about the River

You may have noticed that you can't take your boat any further north than the Stillwater High Bridge. This is due to invasive zebra mussels, which are extremely harmful to the St. Croix's 40 species of native mussels. In an effort to contain zebra mussels, the National Park Service decided to restrict travel any further north of the bridge. The restriction has been extremely effective at limiting the spread of zebra mussels. 

Ways to Protect the River

Always clean, drain, and dry your boat and other recreational equipment if you move between waterbodies. Zebra mussel veligers - the larval life stage of zebra mussels - are microscopic and a single cup of water can transport hundreds of them.

The St. Croix River Association is dedicated to preventing the spread of aquatic invasive species as we protect, restore and celebrate the St. Croix River and its watershed.

Celebrating the First 50 Years!  

2018 marks the 50th anniversary of the Wild & Scenic Rivers Act. From this Act, the St. Croix and the Namekagon rivers became the country's first wild and scenic river national park-the St. Croix National Scenic Riverway. In partnership with the National Park Service and others, the St. Croix River Association will be leading a year of events to raise awareness of the St. Croix National Scenic Riverway and provide recreational opportunities for all. To learn more, visit:
